Application filed May 2 To all whom it may concern.

Be it lznownthat I, ARMIN ELMENDQRE, a citizen of the United States, residing at Chicago, county of Cook, State of: Illinois,

as, for example, the body and cover or head of a box or barrel, made of metal-sheathed boards in a simple and effective manner.

The various features of novelty whereby my invention is characterized will hereinafter he pointed out with particularity in the claims; but, for a full understanding of my invention and of its object and advano with the accompanying drawing, wherein:

tages, reference may be had to the following detailed description taken in connection Figure 1 is a section through a fragment ot a box or barrel and cover separated from each other, the parts being in their-initial preformed condition;

Fig. 2 is a view similar to Fig. 1 illustrating the first step in the process of making the joint, 1

Fig, 3 is a view similar to Figs. 1 and 2,

showing the joint completed;

Fig. 4 is a view similar to Fig. 1 showing a modification;

Fig. 5 is a view similar to Fig. 4 showing the joint completed;

Fig. 6 is a view similar to Fig. 5, illustrating an additional fastening means if one be desired; i

Fig. 7 is a view similar to Figs. 1 and. 4,

showing a still. further modification; and

Fig. 8 is a section showing the completed j oint between the parts illustrated in Fig. 7. Referring to the first three figures of the drawing, 1 represents the wall of a box or body or any othersuitable wall made up of a board having on the exterior a metal sheathing, 2. The metal sheathing is extended beyond one end of the as indicated at 3. 4 is another wall adapted to 1 lie against an edge of the wall 1 and be securely joined thereto;

w all r921. Serial No. arises; v

the member 4 being a head or coverwhere the nremberjl is a box or a barrel. The outer side of the wall4 is covered with a metal sheathing, 5, projecting beyond the periphery of the same, as indicated at 6, a distance equal to the height of the extension orflange, 3, less the thickness of the wall 4. The flange or extension, 6, is bent outwardly at right angles to the plane of the member 4 as illustrated in Fig. 2 so that when the member 4 is set on the member 1 the flanges 3 and 6 engage with each other. Rivets, 7, pass through the flanges 3 and 6 to fasten them together and the double flange is then bent inwardly as indicated 1ion Fig. 3 so as to overlie the top of the mem- In the arrangement shown in Figs. 4 and 5 the sheathing on the member. 1 is extended beyond the end of that member a distance equal to the thickness of the cover member 4, as indicated at 8. The flange, 6, on the cover member is bent downwardly over the edge of the latter. Then when the members 1 and 4 are assembled as indicated in Fig.

5-, the flanges 6 and 8 engagewith each other. C'The joint may be sealed by placing a' line oh solder, 9, between the extreme upper end of the flange 8 and the base of the flange 6. If desired, greater mechanical strength may be given to the joint by inserting nails or screws, 10, through the flanges 8 and 6 and into the body of the member 4.

In Figs. 7 and 8 I have illustrated an arrangement in which a still different type of joint may be obtained. The member 1 with .its flange 3 is the same as in Fig. 1. The cooperating wall or cover, 11, has a sheathing layer, 12, co-extensive with the same. The member 11 is set against the end of the memher 1 within the flange 3 and the marginal portion of the latter which projects beyond the member 11 is then bent inwardly across the top of the latter as shown in Fig.8. The joint maybe sealed by means of a line of solder as indicated at 13, while. greater me" chanical strength may be given to the joint by'means of nails or screws. 14, passing inwa-rdly through the inwardly-bent portion of the flange 3 and through the member 11 into the member 1.

' It will be seen that a box or barrel made in accordance with the disclosure herein will have its joints tightly sealed, will preg sent awholly metallic exterior surface, and

may be assembled quickly and conveniently from parts suitably flanged in the course of manufacture thereof.

lVhile I have illustrated and described only a few specific forms of my invention, 1,

do not desire to be limited to the exact de tails thus illustrated and described; but intend to; cover all forms and arrangements which come within theternis employed in the definitions of my invention constituting the appended claims.

I claim:

1. A structure made up 01" a metalsheathed wall. and a second wall having a face overlying an edge of the former, in which the metal sheathing of the first wall extends outwardly across the. end of the other wall. v

2., In a structure of the character described, two'walls each sheathed with metal on the exterior thereof, said walls being arranged atan angle to each other, one of said walls lying upon an edge of the latter wall,

the sheathing on the latter wall being extended beyond the same past the end of the other wall.

ranged at an angle to each other, one of said walls lying upon an edge of the latter wall, the sheathing on the latter wall being extended. beyond the same and engaging the sheathing on the other wall.

4. In a structure of the character described, two walls each sheathed with metal on the exterior thereof, said walls being arranged at an angle to each other, one of said walls lying upon an edge oi the latter wall, the sheathing on each of said walls being continued beyond the ends of the same in the form of flanges contacting with each other. In testimony whereof, I sign this specification.
